But as of tonight London has a brand new railway system - the Night Tube. It's got its own mascot, namely Becky, the Night Tube owl. It's got its own map, including a paper version you can pick up in stations. And it's got its very own set of superlatives and trivia.

As far as I'm aware TfL doesn't have a special Facts and Figures page for the Night Tube, so I've had a go at coming up with one for myself. I've attempted to match TfL's original list, and added three more facts of my own. Please note that the data only refers to the initial Night Tube on the Central and Victoria lines, not the full five-line system due later in the year. The list may not be 100% accurate, sorry, but I have attempted to be.
